SHAFT-BEARING.

Specification of Letters Patent.

Patented May 23, 1916.

Application led July 7, 1914. Serial No. 849,410.

To all whom it may concern v Be it known that we, JACOB B. PERKINS and HARRY J. SMITH, citizens of the United States, residing at Cleveland and Lakewood, respectively, in the county of Cuyahoga rand State of Ohio, have invented new and useful Improvements in Shaft-Bearings, of which the following is a specification.

This invention relates generally to an oiling bearing in which the bearing basea'nd cap are mounted by a'ball and socket joint on the supporting frame or hanger and more particularly to a bearing of this type in which the shaft is provided with an oiling ring or collar which forms part of the means for distributing the lubricating oil over the journals of the bearing and taking up the longitudinal thrust on the shaft. I n that type of such bearings heretofore 1n use known as long coupled sufficient space was provided between the topvof the cap and the upper bridge of the supporting frame to permitthe cap to be lifted off 'from the collar of the shaft and then removed lengthwise of the shaft from between the latter and supporting frame and still permit this ingy the lupper bridge of the frame close' down tothe upper side of the bearingk cap that the latter cannot be removed aXlally from the shaft inasmuch as this cap embraces the upper part of the Aoiling collar,`

` ,between the journals and with an oil reserand it therefore becomes necessary t o move the shaft bodily in the direction of its axis together with the oiling collar and bearing short coupling or close coupling the supporting frame and bearing cap and base and still permit of ,removing the bearing cap from the shaftand collar as well as assembling the parts inthe reverse order in the same manner without necessitating movf ing the shaft lengthwise in the supporting frame, thereby enabling the shaftV to be facility and convenience and also permitting of inspecting, adjusting or repairing the same more readilyand conveniently.

In the accompanying drawings: Figure 1 is a vertical longitudinal section of a shaft having an oiling ring or collar and mounted in a bearing which is constructed in accordance with our invention, the section being taken in line 1 1, Fig.h 4. Fig. 2 is a vertical longitudinal section ofl the same taken in line 2 2, Fig. 4. Fig. 3 is a horizontal section taken in line 3 3, Fig. 1. Fig. 4 is a vertical transverse section taken in line 4 4, Fig. l.

v Similar characters of reference indicate corresponding parts throughoutl the several views.

1 represents the shaft which is arranged horizontally and provided with a ring or collar which ispreferably constructed in two semi-circular sections 2, 3 and clamped against opposite sides of the shaft so as to form a complete ring or collar which turns with the shaft, the connection between these ring sections being preferably effected by means of bolts 4 which connect the corresponding ends yof the oiling ring sections on opposite sides of the shaft, as shown by full lines in Fig. l and by dotted lines in Fig. 3.

5 represents the base of the bearing which is provided with lower journals` 6, 6V engaging with the underside of the shaft on opposite sides of the oiling ring or collar and also withV a circumferential groover 7 voir 8 which entends from the groove 7 to the opposite ends of the base. The lower part of the oiling ring is arranged in the groove 7 and its opposite sides engage with the inner ends of the journals 6, 6.

9 represents the cap of the bearing which is provided on its inner side about midway4 of `its length with a circumferential groove 10 which receives the upper part of the oil- Q69 latter in its proper yverticalpositiontogether Yhanger bars or arms.

ing its rotary movement and also as a thrust bearing to hold the same againstlengthwise or axial movement. During theV rotary movement of the ring or collar the same picks up the oil in the lower groove 7 between the lower journals 6, 6 and delivers the same into the upper groove 10 of the cap from which last mentioned groove the oil flows through longitudinal channels 12, 12 formed between the opposing edges of the cap and base where the samecomes into contact with the periphery of the shaft for lubricating the latter and the journals while the' surplus returns to the reservoir, in the manner shown and described in the application for patent of H. J. Smith, filed August 7, 1908, Serial #447,374.

On its underside the bearing base is provided about midway of its length in a con- Vex bearing face 13 and on the upper side of the bearing cap the latter isprovided about midway of its lengthwith a convex bearing face 14, said bearing faces of the base and cap being concentric and together forming` parts of the surface of a ball or sphere.

15 represents a lower trunnion provided at its upper end with a concave bearing face 16 `which engages with the convex bearing face of the base and 17 represents an upper trunnion provided at its lower end with a concave bearing face18 which engages with the convex bearing face of the cap, as shown in Figs. 1 and 4.

19 represents a supporting member or frame which is preferably constructed in the form of a hanger and which comprises two upright side bars or arms 20, 20 arranged on opposite sides of the bearing capy and base, a lower bridge 21 arranged transversely below the bearing base and preferably detachably connected with the lower ends of the hanger bars or arms by meansV of screws 2 2, or otherwise, and an upper bridge 23'arranged transversely above the bearing cap and preferably formed integrally with the Between the'upper and lower bridges the hanger bars areprovided with retaining screws 24 which engage Withyertical faces 25 o'n horizontallyv opposite sides of the bearing base forholding land adjusting `the same horizontallyv and laterally in theproperposition within the supporting frame. The lower bridge ofy thesupporting frame isprovided with an upwardly opening socket 26 which receives the lower trunnion and in the bottom of this socket. is arranged a vertical adjusting with the .parts mounted thereon. The up-V pertrunnion is arranged in a downwardly opening socketf28 formed in the upper Y bridgeof the supporting frame and is held*V bridges and the opposing parts of the cap and case is so'close that if the bearing cap were made in one piece, as has beenV customary heretofore, it would be necessary f in mounting the shaft with its collar to first apply the base and cap to the shaft and its collar while the shaft and collar are withdrawn axially fromthe supportingj'frame and the unmounting of the shaft would be similarly effected by first moving the shaft with the collar and bearing cap and base axially out of the supporting frame.; This is objectionable on account Vof the in'convenience, labor and time consumed in thus manipulating the parts. t

In order to facilitate the mounting of they shaft and, its collar in the bearing and also Y yrendering the same more convenient for inspection, adjustment and repairs after theV same are mounted, the bearing cap is ldivided into vtwo sections 30, 30 theV division between these sections being arranged transversely of this cap and preferably. so that the division lineor joint 31 betweenV thev same extends crosswise of this cap through the con-V vex lface thereof and transversely in line with the oiling ringfor collarV onY theshaft and the ygroove 7 kof-,this cap, asshown in Figs. 1, 2 and i3. YOn opposite sides of this joint between the sections of the bearing'cap these, seotions'are provided with transverse flanges` or lugsf32, 32 which are adaptedto be connected with each other byl horizontal longitudinal bolts 33. arrangedV on Vopposite sides of the cap, as shownfin Figs. ,2, 3 and'Y 4,v or byany othersiiitable meansgso that when.` the sections of the cap `are thus conlnected `the .samev form practically onepiece and operate when the shaftfis mountedY to re-V Y. Y

ceive'the thrust of the oiling collar. The sections of this cap are preferablycast Yin L onevpiece lbyusingla splittingcore in'V the mold andafter the cap has been completely babbitted and machined, .the same is divided I `into two pieces vby cracking the-sametransversely about midway between the ends' thereof 'to form `the transverse joint, this being preferably effected by the blow-of a hammer and a splitting wedge. g VIn mounting a shaft -wi-th an oiling collar or ring in a bearing embodying this inven-Y tion the supportingY frames or-hangers are first mounted or suspended Von the wall or ceiling of the building and the alinement of 'Y thesam'e veriliedin; three directions soAtha-tf vthey are plumb and also Vhorizontally i and l' vertically inthe `prtper position: relativelyV toeach other. .'llhershaft is-then'V elevated tov Y if its approximate position in the spaces between the frame arms below the upper bridges thereof after which the lower bridges are secured to the lower ends of the frame bars. The split collar or ring associated with each bearing is then secured loosely to the shaft adjacent to one side of the companion supporting frame, the bearing base is applied to the underside of the shaft and one of the collars and then the bearing base together with the collar are moved axially along the shaft until the base and collar are in such a position within the supporting frame that the convex face of the bearing base is vertically in line with the lower trunnion. The side screws of the hanger frame are now tightened against opposite vertical sides of the bearing base, the clamping screws of the collar or ring are tightened by means of a bent screw driver or other suitable tool, so as to permanently or ixedly secure this ring or collar to the shaft. The two sections of the bearing cap are vnow moved axially toward each other' from opposite sides of the supporting frame so that -the inner ends of these cap sections engage with each other and the journals thereof engage with opposite sides of the oiling ring or collar and the adjacent upper surface of the shaft, in which position these sections of the bearing cap are retained relatively to each other so that they practically form one pieceV by means of the connecting bolts 33. The upper trunnion is now lowered into engagement with'the convexk face of the bearing cap and held in place relatively thereto by tightening the upper clamping screw which is mounted lin the upper bridge of the companion supporting frame. is now completely assembled with theshaft and its collar and these parts are in their proper working condition.

lifhen it is desired to dismount the shaft or to adjust or inspect the bearing it isonly necessary to loosen the upper trunnion clamping screw 29 and to remove the bolts 33 which connect the bearing cap sections after which the two halves of thecapV may be moved outwardly lengthwise'of the shaft in opposite directions and the oil ring loos-V ened or tightened as the case maybe by means of a screw driver or similar instrument after which the cap sections may be again assembled in the manner previously described.

It will be obvious from the foregoing that the advantages of a close coupled ball and socket collar oiling bearing are obtained in this improved construction without any ofv the inconveniences or disadvantages attending the use of this form of bearing as heretofore constructed, but on the contrary this improved bearing possesses all the advantages of the long coupled bearings of this The bearing character and none of thedisadvantages of the latter and without any material increase in cost of manufacture.
